This invention relates to an apparatus for winding upon and unwindingfrom reels a flexible connection or belt which is adapted to be used fordisplaying advertising, for displaying pictures mounted thereon, or forbringing progressively into view any other matter Which can be inscribedupon, carried by, or make up a belt or other flexible connection.

Among the objects of the invention are to provide an improved automaticmeans for keeping the matter to be displayel continuously in motion sothat all portions thereof Will be progressively displayed in an advan-15 tageous manner at the desired rate of speed.

' An important-feature of the invention oonsists Vin an improvedmechanism for causing the power of the motor to be shifted from theoperation of one reel to that of the other reel, so that one reel Willbe stopped and the other reel automatically put into motion at theproper times.

Other objects are to improve apparatus of the class to Which theinvention pertains with respect to simplicity and durability andpositiveness in operation.

Still other objects and advantages may hereinafter appear. Y

Referring to the accompanyingdravvings Which illustrate the invention,

Referring in detail to the drawings, the main' elements of the apparatusare the ilexibleconnection or. displaying belt 9 Winding upon:z'tndfunWindingV from the spaced apart z"reels lQand' 151 VWhich arerespectivelymounted upon vertical shafts12 and 13k and move 59 thedisplaying section of said belt through the exhibition case orcompartment 14. vThe operating means Will now be described in detail.The motor 17 operates the primary driving shaft 1 8 upon which issecured a Worm 19 that is in mesh With a relatively 55 large Worm gearWheel 20. Said Wheel 2O is secured to a main transmission shaft 21 Whichin turn has a pinion vgear 22 secured to it, the latter gear being inmesh With gear teeth 23 formed on a continuously rotating clutch 5.0member 24. On one side of said clutch member 24 is a cooperating clutchmember 25, and on the other side thereof is a'cooperating 4clutch member26. To the cooperating clutch member 25 is secured 'asecondarytransmity65 ting shaft 27, and to the other cooperating clutch member 26is secured a transmitting shaft 28. Said shafts 27 and 28 aline witheach other and have their adjacent ends in close proximity, thusproviding a supportive and bearing for the hub portion 30 ofthe middleclutch member 24.

In order to operate the clutch elements Which have just been described,a clutch operating frame is provided,said frame consisting of theupright arms 31 and 32 Which are respectively pivotallysecured at theirlower ends to the supporting feet orV lugs 33 and 34. The upper ends ofsaidupright arms 31 and 32 are pivotallyV connected to the ends of a 8ocross arm 35 having nearl its center an up- Wardly extending yoke 36whereby said cross arm 35 is shiftedvback and forthv by means of Y acrank 37 Which Vforms apart of a shaft 38 operated by means describedlater.- Thes movements of arms 31 arecontrolled by 'a guide or bracket B(see Figs. 4 and 5) Which is supported from standard S by means of armsT. Y l

The upright clutchshifting arm 31 is pro- 90 vided with a yoke y31awhich embraces a groovedv hub 25a With :which ythe f shift'able clutchelement 25 is provided, and the upright arm'32 is provided with `ayoke'32EL Which cooperateswith a grooved hub 26a with which 95 theclutch element 26 is provided. Thel central, continuously rotatableclutch element 24 is provided with holes Y39 Which are bored ltherethrough as well shoWn-inF-igure 4,A and themeveble @sichelemeetseed 26 er@ te? Vmally to hold the clutchin the neutral positionshown in Fig. 4 wherein said springs 27c and 28c are extended to thelimit of their re-r` siliency. l l

Returning now to the shaft 38 which carries the clutch operating crankarm 37, said Vshaft 38 has fixed thereto a cam plate 45,*said cam platehaving at one side Vof said shaft a segmental portion 46, and at itsother sidel an operating arm 47 which is actu-ated by a lever 48 pivotedbetween itsends to a supporting pivot 49 so asto operate in a verticalplane. The lower end of said leverv 48 is positioned with a part 48athereof between a pair of yoke arms 50, and when said yoke isreciprocated, as will presently be described, said lever is caused tooscillate in such a manner that the upper end thereof sweeps back andforth across the free end of the operating arm 47 of cam plate 45.V Tosaid lever 48 is secured an overthrow spring 55the straight upper endportion55a of said spring extending within a yoke or guide 56 carried bycam plate in order to afford a lost motion operative relation betweensaid spring and cam plate.` Cam plate 45 is provided at one side Vwith astop shoulder 45suwhich cooperates with a stop 8(7), and at'the otherVside with a l stop shoulder 45t which cooperates Vwith a sto 81. Y n

5am plate 45 is provided at one side of its operatingarm 47 withacamusur-face 47 and at the other side of said arm with a camsurface'47b,.andrthe rounded upper end o f the Yoperatinglever- 48sweeps across irstrone and then Vthe other of these c am surfaces inoplerating said cam plate. The coiled lower portion of spring lVisseated upon and secured Yto a stud. 551 which is carriedr by lever i v48 a short distanceabove its supporting pivot .49, This arrangement ofYVsaidspring, cam plate andlever causesa reverse throw to Vbe given tosaidcam plate whenever the adjathe end of the al'soengages sprocketwheel 65' on shaft 28.

-The upright shaft12of reel 10 has fixed to it a bevel gear 12 which isdriven by a bevel gear 12b Vfixed to shaft 28, and the other reel shaft13 has fixed to ita bevel gear 13a which is driven by fabevel gear-13bfixed to shaft 27.

" Y, The exhibitionicase 14 may be shaped and supported in any suitablemanner in order to Y display to advantage the pictures or other mattercarried by the sheet or connection 9.

In the drawingssaid case 14 is shown sup-V ported by the top cross piece7 O of a frame having end pieees or uprights 71 anda base member 72.Said case-14 is. secured to the lower side of top piece by means of aspacing member 73 thus providing room for the top bearings 74 and 75 ofreel shafts 12 ano portion of which is located a lamp 77 adapted toilluminate the exposed portion of the connection9.

In operation, the motor is started-and kept running thus rotatingcontinuously primary shaft 18 carryingI worm 19 which meshes with wormgear wheel 2O fixed to main transmission shaft 21, said maintransmission shaft 21, Vby means of its gear 22 rotates contin- `aouslythe middle clutch member 24. Assuming said clutch member 24 to beengaged by the pins 40 of the left hand shiftable clutch member 25 asseen in Fig. 4, the operation of the motor will cause continuousrotation of the shaft 27, the latter shaft by means of gears 13b and 13Lwill rotate upright shaft 13 ofl reel 11 thus unwinding the sheet 9 fromreel 10'and winding it upon 'reel 11.

The rotation of reel 1() thus 'caused will also rotate reel shaft 12,its gear12a, gear v1 2b and shaft 28. Shaft 28 through sprocket wheelsk65, 61a and sprocket chain 64 will rotate screw shaft 61. Such rotationof screw shaft 61 will move theymember 50i mounted thereon, say towardthe left as seen in Figs. 1 and 6. Continuous left hand movement ofmember 50V together with the lower end ofA lever 48 will cause the upperend of said lever 48 to move toward the end of the cam plate arm 47untily said arm reaches the left hand dotted position of 6 wherein .theshoulder 45s ofthe cam plateA is brought into approximate engagementwith thevstop 80 at which time 'the upper;L

end of lever 48 will free itself fromk the end of arm47 and the spring55will thereupon give a sudden right hand overthrow movenient to the camplate thus bringing-its right hand shoulder 45t into contact with thestop` 81. When this occurs said cam plate will by meansof the shaft. 38to whichit is fixed,

and the crank arm 37 carried by said shaft, (seeFig. 4) actuate thecross bar 35jof the clutch 4shifting frame thus withdrawing the f;

.pm740 of clutch member 25 from the central clutch member24'a'ndat thesame time mov-` engagementi withV the central clutchA member 24; 'i iing the pins40 of the clutch memberf26 Linto plate 41:5 takes place thetraveling member 50 begins to move in the reverse direction along saidscrew shaft 6l.

The various gears are of such arrange 6l will cause the traveling head50 to actuate the cam plate 45, operate the clutch and stop the rotationof one reel and start the rotation of the other when the proper timecomes for doing so, that is to say, after the entire matter to bedisplayed has been run across the display casing.
